Hawkstone’s Big Sandy sedimentary lithium project in the US hosts a big 320,800 tonne lithium carbonate equivalent (LCE) resource.That’s ~$2.5billion of in-ground value from just 4 per cent of a project area that contains ~271.1Mt to 483.15Mt at 1,000 to 2,000ppm lithium.Huge.It’s also located in Arizona along the so-called US ‘Battery Corridor’:

The Big Sandy Project is located on interstate I93 between Phoenix and Las Vegas and comprises 311 Bureau of Land Management (BLM) claims in Arizona, covering approximately 25km2.Development of lithium projects is a priority for Federal US agencies following the signing of the Executive Order ‘Federal Strategy to Ensure Secure and Reliable Supplies of Critical Minerals’ on 20 December 2017. Big Sandy is also of strategic relevance given the Tesla Gigafactory is located approximately 960km by sealed interstate highway to the north-west.Big Sandy is characterised largely by flat-lying basin sediments with analcime and potassic alteration zones. The green lacustrine Lithium bearing sedimentary horizon is traceable for over 11km north to south and extends at least 2km to the east as a flat sheet at or near surface. Faults underlying the lake may have served as channel ways for lithium-rich solutions to percolate into the lake basin and possibly alter and enrich the existing clays in lithium.
